Summary of Smart Aquarium
The project displays status of a previously built smart aquarium: temperature, date/time, and sump water level shown on a color TFT. The original system controls lights and pump via Arduino Uno, Ethernet Shield, ULN2803, relays, and receptacles, plus a servo feeder. The EENG 383 addition adds a second Arduino Uno, Adafruit 1.8" 18-bit Color TFT Shield with Joystick, waterproof temperature sensor, infrared proximity sensor, and a floating platform to present real-time tank data.
Parts used in the Smart Aquarium:
- External power supply
- Arduino Uno (primary)
- Ethernet Shield
- ULN2803 driver
- 4 120V AC relays
- 4 controlled 120V AC receptacles
- Servo motor feeding system
- Arduino Uno (second)
- Adafruit 1.8 inch 18-bit Color TFT Shield with Joystick
- Waterproof temperature sensor
- Infrared proximity sensor
- Floating platform
The goal of our project is to display the status of a previously implemented smart aquarium. The previously implemented system includes an external power supply, Arduino Uno, Ethernet Shield, ULN2803 driver, 4 120V AC relays, and 4 controlled 120V AC receptacles, and a servo motor feeding system.
The four controlled receptacles supply power to three different lighting options and power to the sump pump. The EENG 383 project we implemented provides real time tank information to a full color LCD screen. The system includes a second Arduino Uno, Adafruit 1.8″ 18-bit Color TFT Shield with Joystick, waterproof temperature sensor, infrared proximity sensor, and a floating platform. The goal is to display the tank temperature, date and time, and water level in the sump pump.
